Compare tender drawing revisions and list changes that affect price
We take off your hands: flicking between two sets of drawings looking for what has changed, clouded or not.
You get: a change schedule for each revision with marked-up overlays, sheet references and the trades affected, for your estimator to reprice from.

The problem
The architect changes things without clouding them and we only find out after we've won.
How it works
What comes in
- Previous and revised drawing PDFs, drawing register
What AI does
Aligns sheets, detects visual and text differences, classifies them by trade and writes a change schedule with sheet references.
What you get
- Change schedule per revision with marked-up overlays and affected trades
Who signs it off
Your estimator checks each flagged change and judges what it does to the price.
What it needs to work
- Vector PDFs work best
- Consistent sheet sizes and title blocks
If those aren’t in place yet, you’ll hear that before anything gets built.
Who it’s for
- Main contractors
- Specialist subcontractors
- Surveyors and cost consultants
